Abstract
The low-temperature phase diagram of parahydrogen in one dimension is studied by quantum Monte Carlo simulations, whose results are interpreted within the framework of Luttinger liquid theory. We show that, contrary to what was claimed in a previous study [Phys. Rev. Lett. 85, 2348 (2000)], the equilibrium phase is a crystal. The phase diagram mimics that of parahydrogen in two dimensions, with a single quasicrystaline phase and no quantum phase transition; i.e., it is qualitatively different from that of Helium-four in one dimension.

Eq. (1) corrected (published version has pi at the denominator of the first term of the right hand side, instead of pi squared)
